Smart Kraft SK 3
Switch Mode power supplies type Smart Kraft "Sealed"
Smart Kraft Sealed (SK3) (Switch-Mode Advanced Rectifier Technology) is
an environmentally protected rectifier, developed for the professional
user. Significant features of the rectifier are: high operating reliability
and adaptation to automatic control systems. The rectifier is primarily
designed to provide power to electroplating baths in surface treatment
processes, e.g. printed circuit board plating.
KraftPowercon AB’s
vast experience of electroplating rectifiers using switch technology has
been the platform for developing this series of rectifiers for applications
where a small footprint, high reliability and good current quality are
essential.
The design is based on primary switch technology, a technology
in which KraftPowercon AB has been a pioneer within the electroplating
industry.
| Main features of Smart Kraft SK3 |
| • Robustness |
| • Protected from the electroplating environment |
| • Intended for control/monitoring by an external control system |
| • Low DC ripple |
| • High accuracy |
| • Compact design |
| • High efficiency |
